Twist rate is 1 in 10 RH. I know I said I'd get a write up done today but work conspired against y'all. Didn't get home until 2200. It's first thing on my plate right after work so bear with me.

Any write up?

x2, looking for a range/function report. dad's birthday is coming up and he loves him some 30-06...

These are stupid expensive but .300 Win Mag in an AR is interesting. Nemo Omen.

Thanks for sharing!

Write up is on hold. Had to send it back to the manufacturer and we are not exactly seeing eye to eye on problems.

The sound of feedom is the thump of a 30 cal

Uh-Oh!!!!!

Rifle has been repaired and is on it's way BACK!!

So what was the issue, and what was the repair?

Well it seems that I get to eat a bit of crow on this one. I THOUGHT it was a headspace issue that was causing excessive pressures inside the rifle. However it appears to have been a combination of two items.

This is the exact email I received from them regarding the rifle issues.




So basically when it comes back this weekend it is going to the range with a variety of ammunition this time. Also based on discussions Winchester has caused some issues with 308 rifles so it should get cleared up.

I just need to settle on a couple of loads that have roughly the gas pressure and then we'll see how it goes.

Here's an update.

This is a Noreen Firearms BN-36.

Basically it's an AR pattern rifle chambered in 30-06.
My other term for it is a 21 century M1918 BAR / Colt Monitor.

Recoil is very manageable (little bit more than 5.56 but not much) and it's pretty obscure (less than 1000 made, so far)

22" barrel with a nice muzzle break, 20 round mag and I put a Geisselle Super Dynamic 3Gun trigger on it. Yes it's FAST. Surprisingly well balanced and it's tipping the scales right around 10 pounds with full mag and optics. (Slightly better than my Garand with more firepower)
And MUCH better than an M1918 BAR full loaded out.



Does it have a few teething problems? Yep, adjustable gas block requires setting when you get it.
Still tweaking it but this is pretty much my primary rifle and it will do 2 MOA no problem. (It's a battle rifle not a sniper weapon)

Planning on smoothing the lower receiver, a skeleton stock, better pistol grip, and the bolt charging handle will get enlarged and smoothed with a custom knob (personal preference). Using a magnifier and Eotech because honestly I just don't have a scope good enough to mount on this little beast. (yet)

Here it is next to other tools.



For the smiths/mechanics, uses standard AR-15 parts in most places (fire control / lower receiver) except for the bolt, barrel nut / float tube which is AR-10 based.


Why did I choose it?
I LOVE the 30-06, properly loaded it's just better than a 308 (and German Salazar seems to agree)
During the 2013 great ammo famine I noticed that 5.56 / 308 rounds were just flat out gone. What remained on the shelf? 30-06.
They are planning and working on .270 Winchester and 25-06 chamberings. The other chamberings below will not get offered but they CAN be done according to the owner. I am quite certain there will be a major ajustment to some of the larger ones (heavier spring, definitely adjustment to the gas block, etc)

Also I am planning a few more items
Belt fed modification (I'd love it but that's $4000 minimum at Valkyrie Armory / Ares Armor)
Specialized ammo development
Need to tap and drill the float tube to install picatinny rails (this is now standard on new BN36 rifles)
I am definitely planning on additional uppers ... why?

• 6.5-06
• 8mm Mauser
• 7mm Mauser
• 338-06 A-Square
• 35 Whelen (poor man's magnum)
• 9.3 x 63 (European Big game catridge)
• 375 Whelen
• Also have an Ackley Improved Variant which makes your brass life much longer
• Then there are the Gibbs series of cartridges or possibly even 30-06 JDJ
• All of these will run off a standard 30-06 sized bolt, just need to get an AR-10 barrel chambered accordingly. (and tweak the gas system of course)

NOTE: bump fire stocks will need to be significantly adjusted to allow for proper operation (back end of the AR type frame is slightly different by 1/4-1/2 inch)

Looks cool for sure, and I like that caliber. Have you weighed it yet? I am having a very tough time believing their website showing 8 pounds (thats what a mostly polymer SCAR H weighs).

Not sure what pipe they were smoking when they weight it. It feels a lot closer to ten with everything on it. Either way it's become a VERY handy weapon.

Just checked it (working from home).
With arms extended holding both rifles it's just slightly lighter than my Garand which on the scale shows 10. (The differences are measured in MOA on this scale I have)

Still .... it's MUCH lighter than a BAR or even a colt Monitor
Data from Wikipedia

• 7.25 kg (15.98 lb) (M1918)
• 11 kg (24 lb) (M1922)
• 6.0 kg (13 lb) (Colt Monitor)
• 8.4 kg (19 lb) (M1918A1)
• 8.8 kg (19 lb) (M1918A2)

Now that does include the optics in the picture above (EOTECH 551 [8.8oz] + Sightmark 3X mag [6.7 oz])
... so basically it's a pound lighter (15.5 oz) than a Garand.
(which is then offset by 20 rounds in the mag)

I'll keep it

If I really wanted it that much lighter and handier I'd take the barrel from 22" to 18" (not sure I WANT to do that though). Although I'm not sure how much 4 inches of barrel weighs.

Final thought:
One thing that's interesting about it. Per the builder, it's DESIGNED to use commercially loaded (read HOT) ammo that would choke an unmodified Garand. Considering that the SAAMI specs for the 270 are 65k psi and for the 25-06 are 63k psi, I'll feel comfortable running it a little hot compared to the 30-06 specs (50k psi). Phil Noreen specifically stated that Garand / surplus ammo might run a little under pressure for it. So what I intend to do is run the gas pressure for surplus and then determine the exact number of twists to get the commerical stuff / my reloads to run properly.

How does it shoot? Are you still having issues, or is it reliable?

It shoots like a bloody laser now
My ONLY remaining issue is that the ejector / gas system are causing FTEs ... and that's another tiny little tweak I have to work on (gas block adjustment).

Also I ran tetra-gun all through the lower. Slicked that action RIGHT up

FYI, created a discussion group for this particular rifle. Feel free to lurk or ask questions.

Interesting!
